David Pogue - "Two weeks ago, Apple launched MobileMe, the successor to its.Mac service, which costs $100 a year. Among other benefits, it can keep multiple Macs, PCs and iPhones in sync. E-mail, calendars and address books are wirelessly kept up to date. Very cool idea. When I started testing it on July 10, there were a lot of glitches, especially with the Web-based address book, calendar and e-mail programs. Apple told me that it was having some technical problems, but that they were rapidly being solved. And sure enough, by the 14th, several days after the launch, I was really pounding on it, and it worked as advertised."
